In my book it gives the relationship between voltage and electric field as Vb-Va= -\int _a^{b} E dl which for a positively charged conducting sphere Q simplifies to \frac{Q}{4\pi\epsilon_0} (\frac{1}{b}-\frac{1}{a}) my questions is that shouldn't it be \frac{Q}{4\pi\epsilon_0} (\frac{1}{a}-\frac{1}{b})? The integral turns into \int _b^{a} what am I missing here?
